b. Accredited Investor Status. Such Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D as promulgated by the United States Securities and Exchange Commission (the “SEC”) under the United States Securities Act of 1933, as amended (the “1933 Act”).

c. Investment Purpose. Such Buyer is acquiring the Shares for its own account and not with a view toward, or for resale in connection with, the sale or distribution thereof; provided, however, that by making the representations herein, such Buyer does not agree to hold the Shares for any minimum or other specific term, and reserves the right to dispose of the Shares at any time in accordance with or pursuant to a registration statement or an exemption under the 1933 Act.

THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT, OR PURSUANT TO AN EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF SUCH ACT.

The legend set forth above shall not be removed in respect of the Shares and the Company’s transfer agent shall not issue a stock certificate without such legend to the holder thereof, unless (i) such Shares are registered for resale under the 1933 Act and such Shares have been sold in compliance with applicable prospectus delivery requirements, (ii) such holder provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Shares may be made without registration under the 1933 Act, or (iii) such holder provides the Company with reasonable assurance that the Shares have been sold, assigned or transferred pursuant to Rule 144 under the 1933 Act.

e. No Directed Selling Efforts. The Selling Stockholder, or any person acting on behalf of the Selling Stockholder, has not directed any selling efforts in the United
